7.9 QUEST ITEMS

When you quit or die, you will keep most of your personal items, such as
clothes, vials, backpacks, weapons, armour, and so on. However, you will drop
certain items, such as plants, and all quest-related items. Furthermore,
quest-items (including dead mobile bodies) will reset out of your inventory
every so often, so be sure to be relatively speedy about completing a quest.
The reason this happens is to prevent someone from collecting quest items and
just holding on to them, thus preventing anyone from doing the quests.
